WHY STUMPJUMPER?

In pursuit of pure speed, these XC riders and racers demand the fastest, lightest, and most technologically advanced cross-country hardtails available—the only one with 30 years of history behind it! Whether racing a World Cup or hammering their local trails, these athletes want to pedal hard, climb fast, and beat everyone on the mountain, so they won’t accept the slightest sacrifice in terms of weight, efficiency, agility, or ride quality.


WHAT:
Light, stiff M5 alloy frame with shaped seatstays, PF30 BB, tapered head tube assembly, and Competitive XC geometry.

WHY:
To offer best stiffness-to-weight ratio in its class on a tight budget without sacrificing vertical compliance. Results in high performance with a smooth, controlled ride.

HOW:
M5 alloy frame is hydroformed to create the optimal shape for each tube’s function. The geometry—featuring a tapered head tube assembly, PF30 BB and short chainstays—provides quick, responsive handling and acceleration. The sculpted seatstays have a flatter surface on top and bottom, which increases vertical compliance for comfort but maintains torsionally rigidity.


WHAT:
Roval Control SL 29 and 26 wheelsets with carbon rims (S-Works model only or aftermarket).

WHY:
Reduces weight, increases stiffness and durability, and absorbs impact better than alloy wheels.

HOW:
We designed this ultra-lightweight, carbon 29er wheelset with wide rims to accept large-volume tyres. The carbon rim is stronger and stiffer than alloy, so the wheels remain in-true longer, and absorb impact better. The combination of cross-laced and radial-laced spokes also reduces weight and improves overall strength.


WHAT:
Ultralight FACT IS carbon frame with shaped seatstays, Competitive XC geometry, and slim seatpost.

WHY:
Keeps the bike remarkably light—29” frame weighs less than 1100 grams!—without sacrificing torsional stiffness or vertical compliance. Results in increased speed, comfort, and control over rough terrain.

HOW:
FACT IS construction lets us create complex carbon shapes that maximize stiffness and minimize weight and stress/ alignment issues. The geometry—featuring our tapered uniquely shaped head tube and short chainstays—provides superior handling and snappy acceleration. The shaped seatstays and slimmer seatpost increase vertical compliance.


WHAT:
90mm-travel Brain-modulated fork on mid to high-end models, with dropouts compatible with our proprietary OS28 end caps.

WHY:
Delivers the most efficient climbing and out-of-the-saddle acceleration, while retaining smooth, active suspension when taking hits.

HOW:
Brain technology (inside the fork) senses the difference between rider-induced and bump-induced forces, using an inertia valve and oil flow to regulate suspension. When a rider stands to accelerate, the fork immediately stiffens up, eliminating rider “bob.” But, when taking a hit from a rock or a root, the fork is allowed to compress accordingly. OS28 end caps make the interface between the hub and fork considerably stiffer than standard QRs, making the fork even more efficient and responsive.
